电子节气门的控制程序，MBD模式，可仿真和生成代码，具备很好的参考价值。(Electronic throttle control procedures, MBD model, simulation, and generate code, have a good reference value.)

SIMULATION OF OPTICAL SYSTEM

The ghost images are generally genereated in 3d movies are running because of the angle variation. the removal of ghost images are to be important.

利用Matlab实现矩形波导电磁场分布图的绘制(Using Matlab to achieve a rectangular waveguide electromagnetic field distribution diagram drawing)

利用黄金分割法来求解目标函数的局部极小值。(Functions using golden section method for the minimum.)

功能描述： 小数延迟FIR滤波器，对参考阵元信号signal_ref进行 length(tau) M次延迟，分别得到M个阵元的采样信号 关键问题： 若τ 1.2Ts,则Delay(i) 2,tau_valid(i) 0.2Ts 若τ 0.6Ts,则Delay(i) 1，tau_valid(i) -0.4Ts 当tau_valid(i)>0或<0时，从卷积后的数据y_FIR_delay中取值启示位置不同 函数能够实现输入任意延时tau，输出信号波形与理想波形之间误差很小。( Description: fractional delay FIR filter array element of a reference signal signal_ref performed length (tau) M delay times, respectively, to obtain a sample signal array element M key question: if τ 1.2Ts, then Delay (i ) 2, tau_valid (i) 0.2Ts if τ 0.6Ts, then Delay (i) 1, tau_valid (i) - 0.4Ts when tau_valid (i)> 0 or < 0, the volume data y_FIR_delay product after the Enlightenment values at different positions function can be realized enter any delay error between tau, the output signal waveform and the ideal waveform is small.)
